When you started your Premiere Elements project, which settings did you select? You can see your project settings (but not change them) under the Edit menu. Which project settings are listed?
Versions 11 and 12 of the program set up your project automatically, based on your video specs. But in version 10 and prior, you must set your project up properly in order for your video to work efficiently in your project.
Those look like pretty good settings for working with 1920x1080 GoPro footage.
In Expert view, are you seeing a yellow line above the clips on your timeline? If so, press Enter to render your timeline and see if that smooths out your playback.
It's pretty much impossible to output at MP4 at the exact same specs as your original video. Video editing doesn't work that way. But you can output an optimized MP4.
Which Publish & Share template you use to do this depends on what you're going to do with that MP4: Use it in another project, post it online, send it to a DVD authoring program, etc.
I am not familiar with Expert View in PE 10. In the timeline there were red lines over only transitions, but not over the raw footage. Pressing enter rendered these and turned the red lines to green. This did not correct the jerky output after rendering to MP4 (H264).
The objective of outputting to AVCHD was to have the highest quality video file for playback on my computer, and for playback on a HDTV which picks up the video file through an Apple TV connection.
FYI. When I rendered the video to output to a DVD disc, I used AVCHD format (H264 1920x1080i NTSC Dolby). When this file was played back on a BluRay player that can read AVCHD files, the video was perfect.
That's goood news, BL!
Sure, but it does not solve the problem of jerky playback when output to an AVCHD MP4 file for computer playback.
Did you create this MP4 using Share/Computer/AVCHD with the YouTube HD preset?
As I said, there are several output templates that create MP4s are not all are optimized for computer playback.
No. The jerky video was created using Share/Computer/AVCHD with Preset MP4 (H264 1920x1080p 30).
The following Share/Computer presets do not result in jerky output video;
- AVCHD: M2T (H264 1920x1080i 30) [Not Quicktime file so won't play through Apple TV)
- AVCHD: MP4 (HD 720p 60) [Compressed]
- AVCHD: MP4 (NTSC DV Widescreen) [Very Compressed]
- AVCHD: YouTube Wide HD [Compressed]
- MPEG: MPEG2 (1920x1080i 30) [Won't play in Apple]
- MPEG: HDTV (1080p 29.97 High Quality) [Won't play in Apple]
Exactly. Some of these templates are more intensive to play than others.
So I am left without a high quality playback file that can be played in Apple Quicktime?
Are you suggesting that this PC is not robust enough to play back the file? If so, what would it take (this is already a pretty robust PC)?
If I can play back an M2T file (H264 1920x1080i 30) smoothly, which is about the same file size, why can't I play the MP4 file?
The fact that the playback file jerks at a uniform interval makes me curious. It seems like it is missing a frame every second. Tried rendering at a different frame rate (MP4 H264 1920x1080p 25) which made the jerkiness worse.
In terms of playback, the Share template I recommended should virtually indistinguishable from a higher bit rate version. It is simply optimized for playback rather than data transfer.
You do want something that will play on your computer and port to Apple TV at excellent playback quality, right? The template I recommended will give you at least as high a quality as anything you'll stream or get from iTunes.
Are you recommending the YouTube template?
My concern with this is that the file size is about a fourth the size of the MP4 H264 1920x1080 file, so I cannot believe the quality is as good as the original footage. If I stream this to a 65" HDTV, I suspect I can tell the difference.
I guess the bottom line question is why can't I properly process MP4 H264 files?
I'm not sure what else to tell you, BLipsitt. I've made my recommendations. Use the YouTube SD AVCHD output and you'll get great playback.
If you'd like to post your complete computer specs, maybe we can look into specifics about your playback performance. (BTW, have you downloaded VLC Player and tried it for playback? It's my personal favorite media player.)
Okay, here's an interesting twist. The AVCHD MP4 (H264 HD) files all play smoothly using VLC Player (and Windows Media Player), and are jerky in Quicktime. What's up with that?
And these same MP4 files also stream flawlessly through Apple TV onto my HDTV. Problem seems to be isolated to playback on the PC through Quicktime.
Now you know why VLC is my favorite media player.
Apple's QuickTime Player is way down most editors' lists for an AV player. Unfortunately, PrE relies on it quite a bit. Most install it, then use another player, unless foreced to use QT Player for some reason. Some people go to great length to avoid QT Player, if at all possible.
Personally, I have had it on each of my computers, upgraded to the Pro versions, and have never had an issue, but usually use VLC, or MediaPlayer Classic HC, instead of QT Player, or MS WMP - just not so good.
Thanks for helping me to isolate the problem.
