Thanks Dave. That’s basically what I had figured, but I know some of you guys sometimes have little tricks up your sleeves, but I’ll just have to live with it. As far as the Ki-Pro, I know, from what I heard it was absolutely a delight to work with.
Thanks again Dave.

Those are on my list, but it’s hard to convey that to my superiors where as they are more so looking for an obvious “video” quality difference, more so than those that they may consider “non-essential”. What I mean by that is, I may say, it makes my life a lot easier and some of the hassles we have will go way, but they think $$$. They would probably reply that while yes it would make it easier for you, is it really worth the 3-4G it costs us. But trust me, those are already on my list.

No offense taken. I’m just trying to learn anything I can, some good info and some bad but with comments like yours, it slowly helps me weed out the bad.
Then I must pose a question also. I just rendered a video in 3 different formats .mp4, f4v, and .mov. The .mp4 and .f4v were basically same size (1.6MB & 1.7MB) but the .mov was 10.3MB. Is it because of the default setting of .mov and it’s bitrate? I mean, when exporting the .mov, I get quality settings of (low,med,high,etc..), that is basically dummy settings for bitrate… correct?

If the web guys are not happy with large sizes, be careful of using .mov or .mp4, they tend to be larger, and can be quite larger than a .f4v counterpart. But, from my experience, quality is the trade off as usual.

Tell him to get faster internet connection 🙂 In all seriousness, it could be his connection. Also check the server. Is this your server? A friends host server? An actual company server? If so, big company or small? At my work we use a CDN just for the reason of delivering our videos. The CDN has server locations almost evenly spaced out over the US in major cities so the latency is reduced. I might start to sniff out if it’s a delivery issue because it sounds like you may have fulfilled your obligation.

My bad, I forgot to mention that important aspect. Yeah, I use it for progressive. As for the second part, I assumed the size, which I have to teach myself constantly that that is not a good thing to do.

“File size is primarily determined by duration and data rate. I’m not sure where the myth about frame rate (on it’s own) as a method to determine file size began. It can impact quality and sometimes people will also drop data rate but I don’t want to go there unless asked.”
I’ve heard, again heard that it may differ slightly. By slightly I mean we’re talking about overall size of a few KB because of amount of keyframes. I don’t know if I buy it or not. But like you said, it’s the duration and data rate.

Q: Reduce frame size to half – should i be doing this in ae or squeeze ?
A: I haven’t used squeeze so I will abstain from answering.Q: Reduce fps from 25 to 15 or 12 – is it any good at reducing file size maitaining playback?
A: No frame rate reduction. Keep frame rate same as original for best results. File size shouldn’t differ much if reducing.Q: Since the goal is an flv file, should i be rendering from AE in flv or in an uncompressed format such as AVI or MOV and then convert it to flv within squeeze ?
A: Always keep in uncompressed (or near) format(avi,mov,etc) until putting to final codec,size,etc. NEVER re-compress files ESPECIALLY from FLV to FLV. That would be ridiculously crappy.Q:Compression always CBR (since its for streaming)?
A: I actually use VBR, and it seems to work best for my particular product and method of delivery. I think most would say there is technically no wrong answer as long as it suits what YOU have and need to happen.Q: Is a compressor like SSQ the best tool to reduce the file size ?
A: Have not used and will abstain from answering.Q: And which is the best FLV codec ?
A: Confusion of codec and wrapper. FLV is a wrapper and the codec you usually see is On2 VP6, Sorenson Spark, etc. As far as the best… from what I’ve seen, heard and read, miles may vary so again, what works best for what you need. Try some variations.Q: Any commonly known way to reduce noise while preparing the comp to render within AE?(some filter or some other ae feature i should know about?)
A: I’m with Daniel… ????Q: Im getting 7/9mbytes flv files, could this be considered heavy for web streaming playback?
A: Not heavy, but on the upper end. What bitrate are you using? Codec? Audio bitrate? Etc… I could go on for quite a while.Hope this is of some help.
