PD12 Ultimate last release, strange enough after trimming different video segments when I did produce them they still play about 1sec after the trim....

Bug or need I to care for some settings? I did never notice this behaviour before, same clip format from the same camera, same hardware except I'm using an AMD videocard using catalyst driver version 14.12 I did use just one time before.

Since never noticed this thing I did dig a bit more, PD state a clip duration in timeline is 3s:35, MediaInfo state the produced file duration is 3s:93, the compositing/VFX program I'm using (HitFilm Pro) state 4s:08...

MediaInfo reports Seconds:Milliseconds.

PD uses Seconds:frames. The timeline time display on the Previewer is HH:MM:SS:FF Hours:Minutes:Seconds:frames (frames is dependant on the Frame rate set in preferences). 30 fps = 0-29. 25 fps= 0-24. 60 fps = 0-59.

You may be seeing the difference between number of frames and Milliseconds. Windows 7 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1 GB,256GB SSD,1TB HD.

Unfortunately there is a real difference at the end of every clip.

Both, in time as in first post and in content since the produced video is playing for about another second.

Perhaps, you could attach the text of MediaInfo of produced video, and a screen shot of the project, show the whole screen. Please put the scrubber at the end of the project. So that the preview shows the time of the whole project. Windows 7 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1 GB,256GB SSD,1TB HD.

Maybe I did tracked down the way to avoid the problem, but didn't know the reason, attached the MediaInfo files:


  • the original file (AVC 1440x1080 50i),

  • the first edited version produced with the extra sec following SVRT suggestions (AVC 1440x1080 25i)

  • the version I did produced changing the parameters (AVC 1440x1080 50i).


For some reason SVRT suggested a 25i version and the system adopted it, something today (same system same files, the only difference is I did update video drivers to latest release) it's not possible: SVRT suggestion is not applicable and I did need to put the parameters by hand, discovering the trick.

Strage behaviour.

The Produced - longer.txt does not exist.

The Original.txt is MediaInfo of a 24 seconds 16 frames at 25 fps video.

Your Produced longer is only 3 seconds 12 frames at 50 fps. You have edited the original, so I have no Idea what you trimmed.

The original video is 25 fps, your produced video is 50 fps. MediaInfo is going to report different lengths because of the frame rate difference.

I and unable to know what is going on from the information you have provided.

A screen shot of your Project loaded would help.

Also the actual edited videos that you are comparing would help.

Your Original.txt show a video that is 24 seconds 393 MS. Frame is 25 fps. That translates to the PD time of 00:00:24:16 HH:MM:SS:FF.

Produced-Correct MediaInfo 3 Seconds 578 MS at 50 fps. That translates to the PD time of 00:00:03:12 HH:MM:SS:FF. Windows 7 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1 GB,256GB SSD,1TB HD.

Hello, david445

I see you're having issues with the trimming feature of PD12, clip running beyond the point where trim was made. Perhaps splitting the video at the point where you want the clip to start or end might help. Drag the clip into the timeline, play clip to the point you and it to start, split at that point and delete the preceeding portion(to left of split). Play though to point where you want the clip to end, spit at that point and delete the portion that follows(to right of split). he procerss mat take a bit longer but you'll achieve your desired start and end points. This method certainly works for me.

Cheers!

Neil.

@Carl312 attached the project screenshot and the two produced videos (fist instance longer and second instance correct). The Produced - longer.txt in the older post now is ok.

The odd think is PD allowed me to produce .m2ts clips the first time following SVRT suggestions, and did't allow me to do the same now. Mistery, I really dind't understand why.

@Neil.F.1955 this is what I will do in the VFX program after applying all the effects, being not sure how to produce again all the 36 clips in PD with the same settings as before.

Btw looking at the VFX editor timeline at the bottom you see the audio dropping near the end of the last 4 clips (I did already cut out surplus in the others): this part is where PD produced more video than the trim.

david445, I think I see the answer to the mystery. MediaInfo is reporting the wrong duration of the video. 00088.m2ts is actually 4 seconds and 36ms or 4 Seconds and 9 frames in PD. The frame rate is 25 fps.

MediaInfo is reporting 3s 926 ms, which does not calculate to the same actual length. I would guess that the Header info of the file is wrong.

So all is can say is, if the video works for you do not worry about the MediaInfo report on length.

I did an experiment on 00088.m2ts, the audio and video do not match. The Video is 4s 9 frames in PD 12. I extracted the Audio from that video, the Audio WAV file is 3 seconds 18 frames @ 25 fps in PD 12.

Somehow the audio is shorter than the video, even though PD shows that both the video and audio are the same length when you put 00088.m2ts on the timeline.

Attached is a screen shot of my timeline with 00088.m2ts and its audio file.

Carl312 if you look at both video files you will see a real difference, as stated before. The audio in the original complete file didn't have any problem coming directly from a camcorder.

The PD produced version of the trimmed one does have this strange extra video part, the audio was correctly finishing at the trim end.

Anyway I did resolved the problem cutting out the extra parts into the VFX program.
Still something to verify from Cyberlink IMHO.
