Vegas: How to convert GH2 footage var. 80% 23.976 to 100% 29.97?

[pdxalex]

Hi, I've done a lot of googling, to no avail...

I have some footage recorded with the GH2 in variable mode at 80% (of real-time speed) at 23.976 fps. I need to speed up the footage to real-time 100% (ie 1.25x) and render as 29.97.

Total noob in this regard. How can I speed up the footage exactly 1.25x with best results? I've used the velocity envelope in other projects but can't set it to exactly 125% and speeding up playback rate while experimenting with switches (disable, force, smart resample) doesn't seem to affect output. I still end up with a slow motion (80%) clip rendered at 29.97.

Thanks, any help much appreciated.

right click the clip on the timeline, properties, select disable resample and playback rate: 1.250, push ok

This just means it will play faster the original frames, no additional frames added or resampling done

Poison, thanks for the reply.

I tried this before and didn't notice Vegas was still "filling in" the time difference by looping part of the clip.

For example, my original test footage is 1min in actual time but being recorded at 80% it shows up as roughly 1min 13s. So I select "disable resample" and set playback to 1.25. Result is a clip at 100% realtime... all good... but the length should be only 1min. Instead the rendered video is still 1min 13s... the first 1min is fine, but then vegas fills in another 13s by playing part of the beginning again.

I think this is the cause for my confusion and hope that made sense. How can I just end up with the 1min rendered video?

Thanks.

It's suppose to loop. Trim the end back to 1min

If you play at 125% speed, the duration will be shorter. On the timeline, the clip doesn't "cut" itself automatically. You will see a "notch" right where the loop point is. Just trim it to that point.

Does that make sense ?



The GH2 footage shot in this manner IS 29.97. The difference is there is data in the header that tells the file to playback at 23.976 . Theoretically you should be able to "patch" the file to 29.97, maybe with tsmuxer or other programs before importing, but it's not that much harder doing it this way, and you have access to both speeds (presumably you shot it this way for a reason?)

Yeah, I'll just trim it manually... thanks a lot for your help!
