Greetings, I am trying to stabilize some videos using ‘Mercalli SAL3’ that I have included in a PTE show. I have had some success but still trying to figure out how to use Mercalli to get the best results. But I have come across a bit of a strange result that I’d like some opinions on. I have put in a video clip into the PTE show. I have let PTE convert the clip, with some trimming done. Then, I run this converted clip through the Mercalli program to help stabilize the image. When I then play this video clip in PTE, it does not run smoothly anymore. (But it does run smoothly in Windows Media Player and in VLC). So then I re-convert the previously converted clip and then it run smoothly again in PTE. Here are more details: I start with an original video clip that is in ‘mov’ format. I let PTE 'convert' the clip and I did some trimming in the process. When I convert it in PTE, the format changes to a file with the ‘avi’ extension, DSC_4972.converted.avi, (the Format shows it to be ‘MPEG-4 Visual’). Then I run this file through Mercalli and it comes out with an ‘mp4’ extension, DSC_4972.converted.Merc.mp4, (the Format shows it to be ‘AVC’). But the problem is it then does not run smoothly. I then re-convert it in PTE and the extension goes back to ‘avi’ extension, DSC_4972.converted-Merc.converted.avi, (the Format goes back to ‘MPEG-4 Visual’). And it then runs smoothly in PTE. Please see the attached screenshot. I thought a big change in the bit rate would be causing the problem, not the format, but the bit rates appear to be very close to each other in each file. I would like to know if this result is ‘expected’ or are my steps causing the problem. Thanks… Gary
