Hi

. . . .  D: drive . . . .

What is the D drive an internal second drive, USB external drive or a Memory card/stick, and is it formatted to FAT 32, exFAT, NTFS or a MAC filing system?

I also agree with @AAProds comment:

'I'd be doing a quality-comparison check between an MEPG 4 (H264) export straight out VPX verses the circuitous "Uncompressed AVI>DivXPro>DivX route".'

DivX does nothing that cannot be already done in VPX 15.

For smaller file sizes and no recompression export in VPX using either:

• h.264 encoded video is the most universal format for playback and gives a good perceived (visual) quality for a moderate file size.
   
• HEVC (h.265), which gives a better perceived quality than h.264 with a smaller file size, however encoding/export may take longer depending on your computer system specification - it requires considerably more processing power, and playback devices must support HEVC.

My machine has two SSD drives. One being a 4TB NVMe and a second being an 8TB SATA (that I had referred to as my D: drive).

For reasons unknown when I had output to AVI I ended up with two files initially. I will play around with this some more.

Thank you.

@Jamil-Taylor

Hi

Thanks for the drive information.

I assume the drive is formatted with the NTFS file system, given that the exported files are 700 GB and 200 - 300 GB in size, ie the export is a total of between 900 - 1000 GB.

Why the file was split this way I do not know, there is no limitation coming from the drive file system.

Assuming you are running Windows 10 or 11 on a PC, not a MAC + Parallels + Windows, the video runtime, I calculate about 3.5 - 4 hours, is within the capabilities of VPX and should not be splitting the file.

As has been previously suggested, try exporting direct to MP4 h.264.

@Jamil-Taylor

Magix Movie Studio (and I assume VPX) does export OpenDML AVIs. Open one of your files in Mediainfo and look at the Format Profile; it is "OpenDML". I'm no expert on OpenDML (I use

Okay -- I performed the export and have exact file info. The software again split the exported AVI into two files:

Mediainfo does show OpenDML for just one of the files: SAMPLE_001.avi. The other file it shows no information. It looks like the app quit unexpectedly. The larger file is not even playable.

When I use DivX Pro to combine the two files, it repairs the issue resulting in a playable video.

Here is what Mediainfo shows for the two files. After I convert and combine both using DivX Pro, the resulting divx file is playable. The divx utility repairs the broken video.

This is a Windows 11 Pro workstation with 192GB RAM and a i9 14900K CPU. The export only takes 1.5 hours. Yes -- the file system is NTFS only.

@Jamil-Taylor

Hi

. . . . The larger file is not even playable . . . .

It won't because until the file is correctly closed, the header information is not written to the file header.

An interesting puzzle as to why the file is being split.

When you use DivX to do the final conversion what settings are you using ie:

• Container file format ie AVI, MP4
   
• Codecs for video and audio
   
• Average bitrate
   
• Maximum Bitrate
   
• Quality setting (if there is one)
   

Old versions of VPX did support, when DivX was installed, AVI export with the option to use the DivX encoder, it also supported the Xvid encoder.

I cannot test as the download from DivX is blocked by my Antivirus due to a 'malware'.

John EB

For divx I set it for 2 pass 8220kbps avg bitrate; 320kbps MP3 audio. The resulting quality is actually very good at 9.6GB video file.

@Jamil-Taylor

Hi

Which video codec - h.264 or h.265 etc?

John EB

It's labeled as DivX HEVC 1080p.

Google searching tells me it's H.265: https://www.divx.com/en/software/technologies/hevc/

@Jamil-Taylor

Hi

Have you tried exporting direct from VPX using the HEVC MP4 FullHD 1920x1080 24 fps preset?

The preset is near enough identical to the DivX settings you are using, the Average Bitrate setting is close enough, see note below.

The audio will be encoded as AAC - which is higher quality than MP3.

Note: the Average bitrate is a target for the encoder to achieve, what you actually get will depend on the levels of motion and detail in the video.

John EB

I would like to use DivX Pro that I have been using for quite a long time.

Perhaps I I need to open a support ticket for investigation.

I am trying the export now to see if this works better than the AVI export that failed. The estimated time is not accurate so far, but it appears to be running faster than the AVI export was.

Okay. The MP4 export worked successfully. The AVI export feature is broken in the latest Video Pro X15.

The MP4 export created at a lower video average bitrate is significantly larger than the DivX Pro conversion from lossless Intel AVI.

@Jamil-Taylor

The MP4 export created at a lower video average bitrate is significantly larger than the DivX Pro conversion 

Just go into the advanced Export settings for "HEVC" and change the average bitrate to 8000 (to allow for the audio) and set the max bitrate to 10,000. Change the Coding Quality to Best. Back on the main export screen, type in 23.976 in the frame rate box. Export. Compare quality. 😉

What I am stating is that DivX Pro at 8220kbps avg bitrate created a 9.68GB video file.

The MP4 created was 12GB at only 7000kbps avg bitrate.

The reason I paid for DivX Pro was to get the smallest video files. I want to use it.

@Jamil-Taylor

Hi

. . . . I paid for DivX Pro was to get the smallest video files . . . .

Can you post all the text from the Text view of a MediaInfo analysis of the DivX 9.68GB file.

John EB

I do not want to spend any more time on this.

I simply want AVI export to work. This is a feature offered, and I want to use it.

Here's mediainfo:

@Jamil-Taylor, @AAProds

Hi

. . . .I simply want AVI export to work. This is a feature offered, and I want to use it.. . . .

Unfortunately, the issue with the AVI export splitting the AVI file is preventing this and we cannot determine why it is doing this.

Al and I have been looking at alternative routes to get what you are looking for.

If you wish to continue down the very circuitous route you are trying to use, I would suggest raising a support ticket with Magix.

Click the Support link at the top of this page, select Video Pro X, scroll down to the bottom of the page and select Contact support, fill in the forms presented and scroll down selecting Send email.

Thanks for the MediaInfo data info.

This further complicates the issue, for 2 reasons:

1. the line FileExtension_invalid: avi
    
2. the video is encoded h.263, not h.265 as previously quoted.

This suggests something is wrong with the process in or using DivX. I and another forum member, who has not commented here, have tried downloading DivX codecs from the DivX website, however we cannot install it - the download is being quarantined as containing Malware.

One last thought - if you are wanting h.265 encoded video, to reduce the file size and are not intending to edit the final output, you can, without detriment to the picture quality, use the settings I recommended before for exporting direct from VPX, making one parameter change in the Advanced settings of the export to reduce the file size.

Changing the Maximum GOP length to one of the values listed below will give the following, approximate, file size reductions.

value = 30 ~ 10%

value = 50 ~ 30%

Do not use a value any higher than 50 for the video framerate of 24 fps .

The container file format will be MPEG-4 (.mp4) which means the video will play on the majority of devices supporting h.265 (HEVC) without the need for DivX

@Jamil-Taylor

File size is only function of bitrate and time, nothing else.

What I am stating is that DivX Pro at 8220kbps avg bitrate created a 9.68GB video file.

Not so; your Mediainfo shows the bitrate of your DivX file as only 6251:

If you did a 6251kbps export from Magix, you'd get the same size.

The reason I paid for DivX Pro was to get the smallest video files.

To reduce the file size, all you need to do is lower the export bitrate, regardless of what program you use to create the file.

The real issue is the perceived quality; only you can make that assessment.

I suggest doing a Magix HEVC export at 6000kbps (you don't have to do the whole video, just choose a short range) and compare it with your DivX file. If the quality is the same, you will save yourself time and have a more efficient process.

If you have no resolution on a fix for the Uncompressed AVI export and you still want to go down the AVI>DivX route, you could install the Lagarith lossless AVI codec to export your AVI. LAGS files are around 1/3 of the size of uncompressed AVIs such as IYUV. Hopefully Magix won't split that.

I just did a test export to HEVC using Movie Studio 2024 (small brother of VPX). I set the average bitrate to 6000, max 7500, audio to 192. The export took 18 minutes. File size: 9.74GB.

I appreciate your assistance.

DivX Pro has a setting for 2 pass that analyzes the video during the first pass and applies settings based on the initial review on the second pass. I specifically set it for an average bitrate of 8220kbps:

During analysis the settings get altered; hence 6251kbps was used. Can I manually spend time doing this? I could, but I don't want to. I would prefer DivX do this work for me, and I review the final result.

@Jamil-Taylor

Jamil, I was just pointing out that Magix is doing the right thing with it's file size.

As for why that DivX encoder is settling on 6200 when you told it to use 8200, that doesn't look right to me. After the first (analysis?) pass, it should be setting it's encoding to output 8200, not pick another of it's choosing.

Anyway, we now know that Magix and DivX are producing the correct files sizes; they are different because of the different bitrates being used.

Can I manually spend time doing this? I could, but I don't want to. I would prefer DivX do this work for me.

Well, with Magix, the only thing you have to do is pick a bitrate and off it goes, same as you picking 8220. How you determined that 8220 was good could just as easily have been applied to a Magix export.

@AAProds

Hi Al

How much file size reduction do you get if you increase the GOP setting to 50?

I find this can also reduce file size as I quoted above and has no detrimental effect on perceived quality.

The only issue with increasing the GOP length is should not be edited further.

John EB

@johnebaker @Jamil-Taylor

John, not much! 3MB or so...

@AAProds, @Jamil-Taylor

Hi

After further testing with a variety of scenarios from virtually no action to fast action and, or, high detail the reduction in file size is variable ranging from 30+% to 2-3 %.
