Lin Evans Posted January 13, 2009 Report Share Posted January 13, 2009 http://www.youtube.com/watch?v=URo8OJld840 (1280x720)http://www.youtube.com/watch?v=PBV_oRHT9fI (1600x1200)Judge for yourself. Why support only 1280x720 for auto upload to Youtube??? Switch to "Watch in HD" on both and switch to full screen.Here are specs from Youtube. Recommendations for 1280x720 h.264 BUT this doesn't mean that we can't upload higher resolutions - read carefully: "in general, the higher the resolution the better" Youtube recommends 1280x720 "because" they are a video site. This resolution doesn't work well for us as presentation slideshow users. Yes, we "can" make shows in this aspect ratio but it's a nuisance to have to crop our photos and with Youtube it is NOT necessary to have this aspect ratio to get HD. I was able to get 1600x1200 by using "Custom" and overwriting the maximum of 1080 for the vertical pixel dimensions. After creation, the 1600x1200 MP4 was uploaded to Youtube. Results in link above.....Let's also support higher resolution auto uploads to Youtube in the Upload to Youtube - It's more awkward to have to do it like I did and other aspects ratios are more useful to the majority.Lin Quote Link to comment Share on other sites More sharing options...
Lin Evans Posted January 14, 2009 Author Report Share Posted January 14, 2009 More on the above.... I'm discovering that videos created in sizes greater than 1024x768 in MP4, AVI, etc., will not pan smoothly in the horizontal aspect. Why this is so is a mystery, but it not my system because I belong to a slideshow group on Vimeo and everyone has the same problem and not with just PTE but with "any" slideshow software. If we create a 1280x720 or 1920x1080 or 1200x1600 MP4 or AVI, horizontal pans are jerky. If we drop to 1024x768 HD at 60 fps they appear to be quite satisfactory. I've tried this with multiple systems with the best graphics cards with up to 1 gigabyte of video RAM and it doesn't seem to make any difference. Go larger than 1024x768 and you can expect jerky horizontal pans. Vertical pans are much better. There is still some lack of smoothness, but not nearly as bad as with horizontal pans. Of course when Vimeo or Youtube convert our MP4 uploads to Flash, this jerky movement in horizontal pans is still evident. Right now, I'm uploading a 1024x768 panorama with complete horizontal pan along with zooms. It works very well on my system so we shall see how it fares on Youtube. I will post a link when it's done to get feedback from others. Best regards,Lin Quote Link to comment Share on other sites More sharing options...

Lin Evans Posted January 14, 2009 Author Report Share Posted January 14, 2009 Hi Ken,I just gave up for a couple hours to get some sleep and didn't read your reply until now. There's good news and bad. The good news is that 1024x768 is pretty smooth on the horizontal pans. The bad news is that the conversion to Flash by Vimeo takes its toll on high frequency details over the MP4 at the same resolution.This slide was carefully chosen for the test because it has lots of small detail. The MP4 created at 1024x768 is almost identical in detail to the executable. But converting to Flash softens it noticeably. Flash also introduces the "pulsing" effect which is evident on the Youtube playback.For those interested - here are links to the executable (about 6 meg) and to the 1024x768 Youtube version.Link to executablehttp://www.youtube.com/watch?v=JylVumcoBM0and a link to 1600x1200 version at Youtube:http://www.youtube.com/watch?v=m7O65lUSRw8The bottom line is that at full screen, the difference between 1600x1200 and 1024x768 is quite obvious. To see this, look at the sample of the chipmunk I posted on Youtube. 1600x1200 is virtually identical to the executable for detail even with the softening effects of the Flash conversion. On the other hand, you simply can't pan horizontally without jerky movement at over 1024x768 in the MP4 or in the Flash conversion.The playback at HD quality "without" going to full screen on Youtube at 1024x768 is quite decent. This leads me to suggest that if you want to see your images at incredible resolution on Youtube, make your shows with Video Builder and output at 1600x1200 and the Youtube Flash conversion will be superb. Just don't pan horizontally and all will be extremely good.If you want to pan horizontally, output at 1024x768 and tell your viewers that for best results view at HD without going to full screen on Youtube.My recommendations based on this trial:To get the ultimate quality at 1024x768 you need to upload your MP4 to your own website because there is essentially no serious differences between it and the executable for normal horizontal pans. This apparently means purchasing a player like the Transparent Player to get cross-platform compatibility. Other wise just output your shows for Youtube in HD at 1600x1200 for best results and forget horizontal panning.Best regards,Lingot an "ETA" ?ken Quote Link to comment Share on other sites More sharing options...

backpack45scb Posted November 10, 2009 Report Share Posted November 10, 2009 Lin, have you tried 1600x1200 recently on YouTube? I've been doing some testing of various combinations of my 4x3 originals. I like setting aspect ratio to 16:9, 1280x720 with black borders and specifying HD - high quality video with no cropping. However, when I tried specifying 4x3 aspect ratio and 1600x1200, pte does the upload normally and finishes. I then click done and go to youtube to check results, and no sign of the video. Could be a case of pilot error, but I've done several similar tests with no problem. On those, when I go to youtube, it has text info, and for a while, says the video is loading. Eventually it goes live. Quote Link to comment Share on other sites More sharing options...
