Same As First Video Clip Issues with VS X6

[Back In Black]

Working with a 1080p/60fps mp4 file from my GoPro 3. Trying to save a trimmed clip using "same as first video clip" option. Everything seems to work fine but the saved clip plays for a second and then the video freezes but the audio continues. This happens playing the clip with WMP and VSx6. The original untrimmed mp4 plays fine.

I too have a GoPro Hero 3 Black Edition, and have never had any problems with its footage in X6. In fact, just to check, I just inserted some Hero 3 1080 60p footage and rendered it "Same As First Clip". The rendered video played perfectly in X6, WMP, VLC Player and DVD Fab Media Player. I have other players, but I thought that was enough.

Did you do any editing to the original video? If so, what? Does the resulting video in X6 show exactly the same properties as the original (as of course it should)?

Thank you for responding Ken!

I did no editing. I simply want to extract 20 seconds of footage from the original 17+ minute long clip. The properties are the same except for the video data rate and total bitrate. They are slightly different. ~900kbps difference. The audio bitrate is also a little off between the two.

I did some more experimenting. I did the same process using a clip I shot at the same time using my older GoPro HD. Also a 1080p recording but 30fps vs. 60. I extracted the same piece of footage and saved it using "same as first clip" and it plays perfectly. Now here is where it gets interesting, at least for me. I'm a neophyte when it comes to this stuff. If I trim the first 1 second of the original 60fps mp4, leave it on the timeline and then add the 20 second clip that I'm really interested, save using "same as first video clip", it plays perfectly. I started off with a larger clip from the beginning initially and kept trimming it back until I was left with 1 second. This will get me by for now for what I need the clip for but I'd rather not have that 1 second of useless video at the beginning.

That does sound strange, since normally "Same As" renders to identical properties.

Have you tried the same thing with other 60p footage -- say, shot on a different day -- and cut out a short piece as you have done with this project? Do you still have the problem?

Hello,

You can easily get rid of the 1 sec of video at the beginning that you don't want. I also sometimes use the same method to create video output files with bitrates that I can't achieve through the normal Make Template option.

Here's how. When you're ready to create the output file:

1) Click on the second clip in the timeline, that's the one after the 1-sec clip. This should put the scrubber at the beginning of the second clip, the first frame of this clip. It's also the first frame after the end of the 1-sec clip.

2) Click on the word "Project" under the video display in the preview window.

3) Click on the left bracket "[" in the preview window. It's to the left of the scissors symbol. You should see an orange bar appear across the top of the entire video in the timeline except for the 1-sec clip at the beginning.

4) Now create your output as usual, but before you press the "Save" button to render your video, do the following: Press the "Options" button, click in the small circle next to "Preview range." A black dot should appear in the circle. Then press "OK." Now when you press "Save" to render your video, only the part of the video under the orange line will be created and the 1-sec clip will not appear at the beginning!

Btw, you can just save the 1-sec clip by dragging it into the library, then reuse it over and over again. After you've finished editing your video, just insert it into the beginning of the timeline.

First time using the new GoPro 3 so I only have clips from that day. However, I tried several other clips and they all do the same thing.

Man, I thought you were on to something there but that doesn't work either.

I even tried leaving the original clip intact on the timeline and simply set the in and out markers at the portion of the clip I want to save and rendered that way. The "Preview Range" option is greyed out but it still only renders that 20 second portion that I bracketed. Same result.

Hi

Can you upload a sample clip to a sharing site, 4shared, SkyDrive etc

We could download and try on our pc’s.

Ken uses similar/same types without problems, I’m sure he will download your sample, as will I.
However I do not have the GoPro camera nor the codec as I can't installed the software that came with the camera, But will give a sample a go.

[Ken Berry]

In fact no software came with the camera. I just use what was already on the computer via Microsoft and Corel...

But yes, having a sample of Back in Black's video might help -- though AFAIK it will be identical to mine since it comes from the identical camera and using identical properties...

If I trim the first 1 second of the original 60fps mp4, leave it on the timeline and then add the 20 second clip that I'm really interested, save using "same as first video clip", it plays perfectly.

Did you choose "Same as first clip" like you did before? When you say that doesn't work either, do you mean that the 1-sec clip at the beginning is still included in the output, or that the 1-sec is not included anymore but the video no longer plays perfectly?

Yes I did. The 1-second clip is not included but the video still does not play. I did exactly what you suggested.

I finally got one of the original clips uploaded for you guys to check out if you like. SkyDrive was having issues so I uploaded to Google Drive. I also uploaded the broken file (at least for me). I'd be interested to hear if it plays correctly for someone else. Here are the links:

It's not totally clear from your last post, but which of those uploads is which --though I am assuming they are in the order you mention them? I have downloaded both. Boy, but test.mp4 was huge! (1.7 GB). But I put it in my X6 and used Share > Create Video File > Same As First Clip, and it worked fine. The bulk of the rendering was fast (SmartRender), but at the very end, showing 99%, there was over 1 minute wait before the rendering completed. But it did complete, and the rendered video was identical in every Property, and quality, to the original. Video and audio played perfectly.

I confirm, however, that Test2.mp4 showed a still image in Clip mode, and black screen (which later froze the program for a while, though it unfroze) in Project mode. In both Clip and Project Mode, the audio appeared to play fine. I also tried rendering (Same As First Clip) and it produced the same useless, static result. Yet I can see no obvious difference between test and test2...

In scrubbing across the clip in Clip mode, however, I got a message saying "Frame 479 is unreadable", and after that, further scrubbing similar messages were received for subsequent frames. This would appear to indicate that there is a corruption in that particular bit of footage which is causing the problem.

Just to cross check, I then inserted test2.mp4 into other NLE programs I have. All of them clearly indicated that the video is corrupt. Sony Movie Studio 12 Platinum in fact played the video with full action and audio nearly all the way throughout, though the top quarter inch of the preview screen was filled with heavy blocks of multi-coloured pixelation, and in the last two seconds the screen turned green. Cyberlink Power Director 11 would not even show any image when playing the video, though the audio was again fine. Instead, the whole preview screen was filled with a rainbow of vertical coloured lines throughout the clip. Magix Movie Edit Pro 2013 was similar to Sony in that it played the clip in full action and audio, but with the difference that the first few seconds had a green strobing effect, but throughout it also had the same quarter inch or so of heavy pixelation at the top of the preview screen. So again all I can say is that there is obviously something seriously wrong with that piece of video.

Hi Ken

Well I am having many problems in playing the sample, I assume Test.mp4 to be the original.

My pc is certainly having trouble reading the video, I tried AVS converter that took so long to complete that I cancelled the process.

Using Video Studio and Smart Proxy --- Well this is also taking ages to complete the proxy file, I mean a long time, hours, As I write the file has just completed
However I am now seeing an improvement in Project Playback, Clip playback no change playback is slower and repeatedly stalls, as described by the OP.

Scrubbing the timeline now seems ok, but that’s Project mode.
Like you Ken I was able to render using Same as First clip in a reasonable time as described by you.
Now I have to wait for the proxy file to be created before I can play this file.

[Ken Berry]

Can you confirm you are talking about test.mp4 in all your above comments. Or is it test2.mp4 which is also giving you problems? As I indicated, test.mp4 gave me no problems at all, and I didn't have to resort to SmartProxy...

Hi Ken

I am testing the file ---Test.mp4
File size 1.780,660KB

I have not tried using test2.mp4 a yet, (62,650Kb) I assumed that to be the one rendered by Back In Black
