Nope.

If you could use XAVC-I, it will not re-compress edits that are cuts only.

Thank you guys for the input. Concerning XAVC I, I rendered out a sample and I rendered out a Intermediate 422 and gave to a MAC user and when we compared them and there was a strange anomaly.

The XAVC I picture was a wee bit shorter at the bottom. meaning compressed in picture height, but. not evenly compressed. side by side the top third of the Prores and XAVC were identical but the lower 2/3rds of the XAVC I was progressively more compressed. compressed (meaning in picture Height). The further down the pic the more distortion. ? so if you were cutting be tween pictures it seems to jump at the bottom, but the top you see no change, in the clanging of shot. They were rendered identical settings and clip in a batch render. Theoretically switching between the two identically rendered clips you should see no movement of identical shots. i would expect maybe some color shift but not distortion in the picture. So I am afraid the XAVC I to send files to a mac user. I do not have a clue the cause. So I guess we will fly with Intermediate 422 HQ

@don-c Any chance you mismatched the frame size on the xavc-I? Just tried to duplicate the issue and the only way I could do it was to render a 4096x2160 source clip as 3840x2160 (or vice versa) . I compared them by creating a source clip with the small checkerboard media generator, rendered it, put it on the timeline and then did a bunch of test renders. Then threw them all onto the timeline and cross-faded them. All perfect except the mismatched clip which generates interference patterns during the on cross-fade. Like this:

Fwiw, Xavc-I is 10-bit. Magix-I is not.

I cannot say it was not human error. So I will redo and see if it repeats because I deleted the other. will post the results (if it repeats) so maybe we can figure the problem.

@don-c @Howard-Vigorita

I created a 32 bit UHD project in Vegas 17-452 with checkerboard pattern and rendered using the Magix Intermediate and XAVC-I. Placing the rendered files back on the Vegas Pro timeline and using compositing difference, I could see no significant difference in the Videoscopes. I'll make no statement about what a Mac user might see.

I did the test With Exactly the same settings and they match on the PC. but, when I open the files on a MAC THE XAVC I actually stretches down at bottom. I compared the Intermediate 422 and A CForm MOV and XAVC I they match on PC but on the MAC The XAVC I stretches down. THE CF.mov and Intermediate 422 match on mac. So I took a video of it with my Iphone of me muting the mov file track off and on so you can see the jump on the MAC. i uploaded a clip and you can see what I am saying. Notice the word "james" at the top does not change , but the word "death" at the bottom drops dramatically. I would prefer to use XAVC I because I think it is less problematic than a QT MOV with vegas? Am I correct or is that a "use to be" fact?

don-c wrote on 7/29/2020, 9:18 PM

The case is solved.

First the codec XAVC I is fine on MAC
Second I learned something NEW. It was davinchi Resolve 16 FREE version.
The differences in DR 16 FREE and STUDIO are more than the things they list, it may be a glitch in the FREE version.

Because i am not proficient on FCP X i did not actually check the clip in FCP I used a FREE installed version of DR 16. When you sent the clip I decided to try FCPX and the clips were fine! Then I tried DR16 FREE on same MAC the jump was back. Then I went to another mac with DR!6 STUDIO Paid version they worked fine. So then we install the paid version on the MAC that had the free version, the clips worked fine.

SO it is the free version of DR16 of which we had the latest update.

Thank You for your help!!!!!!

Now may i ask a question? Is XAVC I plenty good for a Three round trip of render? and if I understand correctly DR16 Vegas 17 and FCPX skip re-compressing where not necessary?

Thank You Again

This may be the wrong thread, but I'm going round in circles trying to figure how to perform a "smart render" in the first place.

I have some footage that I am just topping and tailing and/or cutting out certain clips. Everything is the same. The format happens to be MP4 (for screen captures) or MTS (Canon video footage) and I'd like the output to be exactly the same format.

How do I achieve that?

I've tried to match up the size, frame rate, etc. but the rendered file is either lower quality (yet the same file size) or the same quality but many times bigger in size.

Mpeg2 is the only format that supports it.
