Hi.

@Former user is correct. The speed at which a rendered/exported file will play is embedded into the header of the file although you can ask a player to play it back at a slower speed but anyone would have to do that each time the file was played.

As Gid pointed out, it should be altered at the editing stage Using the speed video effect or stretching as Gid described. [There is a stretch mode for the mouse on the lower tool bar where the mouse options reside]

Changing the speed of any video clip may have an undesired affect to the sound as it too should be slowed down. How good that sounds may depend on the quality of the sound recorded on the clip.

OK sounds like I need to use a 3rd party SW to do (to resulting MP4 file) it then

@john-x

I'm now confused as to what you want to do.

The speed of any video can be altered and exported to a desired speed. I do it all the time to co-ordinate dance step videos to music. Sometimes several at once.

The speed at which an existing video plays back at cannot be altered to a different speed by any software without a re-encode as far as I'm aware.

Ray.

@john-x I agree with @CubeAce, unless we're misunderstanding you I don't think you'll find a 3rd party SW. If you do find something & we are misunderstanding there's a good chance it won't work in MMS, def not at the whole movie level, it'd have to be applied on to each clip. & 100% there's no 3rd party SW that changes MMS's export options.

Pls keep this post updated if you do find what you're after 👍

@john-x

John, the speed is changed with the Effects Tab>Video Effects>Speed control. You can apply it to all your video clips at once by selecting them all (lasso them or CTRL Click each one) then applying the Speed effect. If you increase the speed more than 4x, you must ungroup the audio from the video.

As previously mentioned, you can use the Object Stretch mouse mode to stretch individual clips/objects.

Alternatively, export your movie as a high-bitrate MPEG 4 (to minimise generation-loss) then re-import that into Magix and apply the desired speed as above.

Obviously, the audio will be sped up too.

@john-x

Hi,

Further to the other answers, just do what @AAProds suggests, export (I suggest to Magix mxv) and import that to a second movie tab, then change the speed with all of its inherent problems, like sound.

As for another program, it simpler to do in VPX. Just open a second Movie (2) and drag the first Movie (1) onto the timeline - it becomes a single object. Then apply Speed, export. Any changes to Movie 1 will automatically update the object on the timeline of Movie 2.

@AAProds

Hi Al,

You can apply it to all your video clips at once by selecting them all (lasso them or CTRL Click each one) then applying the Speed effect.

In VPX, selecting all and applying a speed adjustment only modified the objects on track 1 (and audio on track 2). I didn't try this in Movie Studio.

Thanks John,

Version 2: MMS 2024 you can change the speed on all selected objects on any track (provided they are on the same track).

@browj2

Hi John

. . . . In VPX, selecting all and applying a speed adjustment only modified the objects on track 1 (and audio on track 2) . . .

Works fine on any track combination for me in VPX 15 including this one.

@AAProds @browj2 @johnebaker @Former user @john-x

In the video I posted above, at time frame 51secs, all three clips are on different tracks with different speed adjustments to fit the audio track. I have never had problems adjusting the speed of any individual clip where needed on any track. It is even possible to speed up and slow down any track at specific points.

Ray.

Selecting all & changing the speed works whether that be in the main movie or a secondary one but what's the point, it screws up all positioning & transitions, The only use would be if you've got a bunch of clips you want to alter the speed of before editing.

@Former user

The OP asked a question and we've answered it. No need to second-guess why they want to do it.

@Former user

Hi

. . . . it screws up all positioning & transitions . . . .

Try changing the speed on multiple clips after setting the mouse mode to single track or all tracks mode as required.

John EB

@johnebaker

Hi John EB,

Works fine on any track combination for me in VPX 15 including this one.

Only with your easy setup. Try something more complicated - add a title with effects, like Opening/Closing Atomar(Intro), cross-fades, and some image with SPR effects.

Select all, change speed to 0.6. Title on track 4 does not change duration and speed is still 1. The 2 images did not change speed. The transition is a mess and there is a second transition where none should be.

Undo and change to mouse mode for all tracks, select all, change speed to 0.6.

Title on track 4 does not change duration and speed is still 1. The 2 images did not change speed and a gap opened up before them. The transition length did not change but remained at 2s (1:29) The video on track 5 changed speed but not consistent with the duration of the clip on track 1 from the end of the transition to the end of the clip.

Playing around a bit more will freeze VPX requiring Task Manager to close it.

So basically, it's a mess and the only way to do this easily is as I mentioned, export/import and change the speed, or, in VPX only, nest the first Movie.

@Former user

Hi,

Selecting all & changing the speed works whether that be in the main movie or a secondary one but what's the point, it screws up all positioning & transitions, 

I don't know why you say that - the two methods give entirely different results. If you export and then import that and change the speed of that, it will work. I just said to import to another movie in the same project for convenience, no need for a different project.

In VPX, no need to export/import, just nest the first Movie in a second Movie and change the speed of that. MMS does not do nesting, VPX does. The entire video changes appropriately - transitions and effects just get shorter or longer.

Go back to the first movie, make changes, switch to the nested movie and the changes will have been applied.

Hi John

. . . . change speed to 0.6. Title on track 4 does not change duration and speed is still 1. The 2 images did not change speed.  . . .

That is the correct behaviour and has been so from about 2014 - despite what the dialog erroneously says for the Speed effect, it works only on video, images have their own option 'Change photo length', Titles, have neither and need to be dragged to length, audio has the Time stretch/Resample option, and of course there is the Object stretch mouse mode which works for all the object types - the latter I find I am now using more during editing and sorting clips etc into order.

This is the Speed effect error message from MEP 2015 when you try to apply it to images, titles and audio - I do not have an old version of VPX to check.

IMHO it is a question of workflow, there are a few effects that should be applied during the initial edit before adding any effects, transitions, titles etc, the Speed effect being one of them, similarly there are effects such as Sharpening which should be applied last either global, track or object wise.

John EB

@johnebaker

Hi John EB,

Right, which means that one cannot just simply apply Speed to all objects in a movie with titles and effects and hope to have a different overall speed with no problems, as @john-x would like.
