How to zoom in on a video?

How can I zoom in on a video? The video was shot from VERY far away with no zoom. — Preceding unsigned comment added by 2602:306:8051:4D60:1449:B59E:A166:DCD9 (talk) 06:37, 12 June 2014 (UTC)

Use a program like Adobe Premiere to permanently zoom in and alter the video. You could also use an open-source video editing tool. Some players such as VLC will allow you to zoom in on played video. Bear in mind that zooming doesn't add extra detail. Zzubnik (talk) 13:54, 12 June 2014 (UTC)

How to convert MPEG-4 into MPEG-2

I have a video that was saved as MPEG-4 & when I tried to watch it on my TV (by plugging a USB into the back of the TV), a message box say that the video is in the wrong format. I read the manual & found that the TV only supports "MPEG-1/2", I guessing means MPEG-1 or 2. I've looked for several websites to try & convert it into MPEG-2, but it either takes to long (I use the computers in the library & only have 3X1 hour sessions on the computer), or need to download/ install something (which I can't do on the library computers). Does anyone have any better ideas ? 194.74.238.6 (talk) 13:58, 12 June 2014 (UTC)

My understanding is that transcoding video is inherently computationally intensive. No matter what, it's relatively slow. See e.g. Comparison_of_video_converters for software that can do it. I've used FFMpeg in the past for similar tasks. It is free and open source, but will require some training to use properly. It looks like encoding.com might allow you to upload your file, have them work on it, and you download the new file later. SemanticMantis (talk) 14:24, 12 June 2014 (UTC)

I've found that Handbrake is very fast with converting, and is free. Zzubnik (talk) 14:57, 12 June 2014 (UTC)

It usually takes long to convert a video - and encoding.com looks expensive, if I'm reading it right. If you only have one video that needs converted, and don't mind giving me a copy, I'll do it for you - we'd need to communicate over email, just drop me a line on my talk page and we can set it up. Otherwise, best of luck:-)Phoenixia1177 (talk) 09:42, 13 June 2014 (UTC)

Film transition. -- Finlay McWalterᚠTalk 15:51, 12 June 2014 (UTC)

Thank you very much. This video uses such a wide variety of film transitions that I suppose that there could be an extensive glossary, covering many more terms than the ones in that article. Wikipedia does not have, at this time, a glossary of film transition. Where, on the WWW, can I find a glossary of film transition?

A list of effects (which can be used in transitions) available in the default install of Adobe Premiere Pro is here. -- Finlay McWalterᚠTalk 19:30, 12 June 2014 (UTC)

Thank you for your reply, which also answered a third question that I was considering ("Is there a software program for producing film transitions?").
