Hiya All,
I bought Magix some time ago and I'm really looking to spend some time producing movies. I have a couple of GoPro and DJI products and recorded a lot of footage the other day in 2.7k 30fps, which is 2704 x 1520 apparently but I can't see any support for that in the movie settings? Any help pointing me in the right direction would be really appreciated.
Thanks,
Duncan
When you say you bought Magix, do you mean you bought the company or just one of their products? If so which one was it?😉
Assuming you bought one of the editing programmes, have you tried just importing your footage into a new project? You will normally get a popup asking if you want to use your footage as it is or adjust it to whatever programme settings you have selected.

Haha! 😂 Sorry Roger, I'm new to the forums and it says to my screen I posted to the Movie Edit Pro section of the forum. I should have said but thanks very much for coming back to me. 😕
I had previously done as you suggested and it appeared to work but my mp4 exports are horrible. I've watched a youtube video from a guy this morning and I'm exporting right now, so hopefully there will be some improvement.
Hi
See this topic and come back with the information requested.
. . . . 2.7k 30fps, which is 2704 x 1520 . . . .
This is not a 'standard' resolution for which there is a preset in Photostory, Movie Edit Pro or Video Pro X.
Until we know which program and version number you have we can only give you a generic answer.

Hi John,
I'm using Movie Edit Pro Plus, latest version I assume as I always allow it to update.
Hopefully I've managed to fix the pixelated output (I'll know for sure soon) but that is going to be at 1920 x 1080 using the program presets. I was wondering what the output settings should be for the 2.7 I was trying to use?
Hi Duncan,
The output settings can be whatever you choose for the final render. Presumably you are looking at 1920x1080 for your output, so you need to decide what output settings you use. As I am in PAL land, I usually output long wedding files in up to 55 minute sections. To do this I use HD Pal 25fps from the export movie as an MP4 tab under the file drop down. In the advanced menu of that drop down, I use variable BR with 10000kbs min and 14000kbs max. That gives a good compromise in quality for the length of files I am using. You could also use that for Youtube, or possibly less, but see what youtube recommends. For shorter files for tv watching I would usually use the default setting which is a higher BR.
Incidentally, I do sometimes use 2.7k video from my GoPro or Yi4K, and drop that into the same timeline as my 4k video. Magix video software is quite tolerant of mixed formats.

Poor output quality is often due to low bitrate for export. I like to use MediaInfo (freeware utility) to find the bit rate of source video and set export to similar. Setting a lower bit rate will result in reduced quality but setting a higher bit rate than the source will not result in better quality than source.

The only problem with that comes when you need to deliver long files on usb. So if I was to deliver my wedding videos at the bitrate I record it at, the files for the client would be reduced to about 6 minutes each, which wouldn't be acceptable for a two hour production.

Thanks so much to everyone for the help you are giving. I'm enjoying the learning curve.
So in the sample I have attached my optimum export Maximum bit rate would be 60000? Is there a formula to know know what the average bit rate should be? Sorry if I'm being dumb, I'm just wondering how the export setting relate to each other.
Of course, you need to consider your intended use. You might not want the best quality for uploading to Youtube or running off a flash drive. You should export at various bit rates and compare the videos. There is a point of diminishing returns and you can select a combo that yields acceptable quality at reasonable filesize. Here is a guide for determining bit rate. https://www.ezs3.com/public/What_bitrate_should_I_use_when_encoding_my_video_How_do_I_optimize_my_video_for_the_web.cfm
Hi
I would recommend you use the default preset export settings as these are already optimised for quality vs file size. Increasing the bitrates gives a rapidly diminishing return in visual quality compared to the increase in file size.
As far as Youtube, Vimeo etc they will re-render your video to several different resolutions, as low as 240p, to enable delivery to be maximised for different devices and Internet connection speeds.
Youtubes recommended settings are here.

If you intend to put your exported mp4 video onto a usb stick, then the most widely readable formatting for the usb would be FAT32. This would then be readable by nearly all equipment including tvs, however, there will be a file limit size of 4Gb. So using your optimum bitrate of 60mbs, would give you a maximum file length of about 10mins. So if you wanted a longer continuous file length, you would have to reduce the bitrate proportionately. you could use alternative usb formatting such as NTSF or ExFat, to accomodate larger files, but would then have restricted playability on a lot of equipment, particularly tvs. There are many variables and it really is a matter of finding what is best for your own particular requirements.

Hi Duncan

That is 60 megabits per second in your Media info screenshot and it is the Average bit rate. The average bit rate is what roughly determines your file size in the encoder settings. Maximum bit rate can be set close to this if you want the file size to remain calculable, or set higher to accommodate a few frames in the stream with a lot of detail or action, to prevent them becoming blocky. If there are a lot of complex frames then this will increase the data stream (Mbps) and increase the file size accordingly.
I presume the Media info is from your 2.7K camera original and that you intend to export it as 1920x1080 res. If so, what you should look at is keeping roughly the same compression factor indicated by the "bits/(pixel*frame)" reported in M.I., calculated from the bits per second 60,000,000 divided by (2704x1520pixelsx29.97fps) = .487, to roughly keep the same level of compression ie quality. So substituting the lower resolution of 1920x1080 in the above equation you would need only a BR of 30Mbps to not increase the compression factor and increase artifacts in the export. Having said that though, you could get away with somewhat lower than .487 with H.264 MPEG4 and not notice the difference depending on content.
There is no guideline as to what average bitrate to use as it depends on the complexity of the content of the video, and what restrictions there are on the data rate of the target medium or platform as others have commented, but if bandwidth or file size is not important, as a rule use whatever parameters you can glean from a Media Info analysis of you original camera file and match the advanced encoder settings to those.
