Use SEQ_time_strip_intersects_frame function to test if strip intersects with frame.
Note: There are cases where this function should not be used. For example splitting
strips require at least 1 frame "inside" strip. Another example is drawing, where
playhead technically doesn't intersect strip, but it is rendered, because current

When sound strip is above another strip such as movie strip, it prevents

This bug was introduced in 0b7744f4da. Function `must_render_strip()`
checks if there is any strip with `SEQ_BLEND_REPLACE` blending and
considers this strip as lowest strip in stack. Sound strips do have this
blend mode set, which caused the bug.

Due to misunderstanding of how strip duplication works, animation data
was duplicated on all strips when any strip was split.
`SEQ_sequence_base_dupli_recursive()` duplicated data on strip that was
being split, and `SEQ_ensure_unique_name()` duplicated animation on all
strips.
Only duplication should be done with `SEQ_ensure_unique_name()` and only
on right side split strips, because only these strips are duplicated.
Fix issue described in T87678, which was partially a bug and partially
change in intended(at least as far as I can tell) behaior.
Function `evaluate_seq_frame_gen` that was partially responsible for
filtering strips in stack for rendering wasn't working correctly.
Intended functionality seems to be removing all effect inputs from stack
as it is unlikely that user would want these to be blended in. However
there was logic to exclude effects placed into same input, which because
of weak implementation caused, that any effect input, that is effect as
well will be considered to be part of stack to be blended in.
This bug was apparently used to produce effects like glow over original
image.
Even though this is originally unintended, I have kept this logic, but
I have made it explicit.
Another change is request made in T87678 to make it possible to keep
effect inputs as part of stack when they are placed above the effect,
which would imply that blending is intended. This change is again
explicitly defined.
Whole implementation has been refactored, so logic is consolidated
and code should be as explicit as possible and more readable.
`must_render_strip function` may be still quite hard to read, not sure
if I can make it nicer.
Last change is for remove gaps feature code - it used same rendering
code, which may be reason why its logic was split in first place.
Now it uses sequencer iterator, which will definitely be faster than
original code, but I could have used `LISTBASE_FOREACH` in this case.

Splitting of effect strip alone wasn't handled properly. Previously
this resulted in duplicating effect strip, and it was broken at least
from 2.79.
Change in rB8ec6b34b8eb2 was intended to allow splitting strips
individually, so it can be used as RNA API function but also so it
requires as little glue logic as possible.
This is fixed by splitting all dependent strips at once in 2 separate
ListBases for left and right strips. Strips can be finally moved into
original `ListBase`.
With this fix it is still possible to split strips individually with
little glue logic. RNA API function could return list of split strips
as well, currently at least one strip in chain will be provided so
chain can be reconstructed on python side.

This iterator design provides means to create simple and flexible API
to query and work with collection of strips. It should be used in cases
when conditions require multiple stages of recursive iteration of all
strips or similar complex scenarios.
Quick API overview:
Basic queries are standalone functions that return SeqCollection
Use SEQ_collection_create() and SEQ_collection_free() to construct
such query functions.
Use these functions to get strips of known conditions, like selected
strips, movie strips, muted strips and so on.
Use SEQ_reference_query() when querying strips with relation to
some reference strip. For example to get its effects, strips that have
same type or use same input file and so on.
These aren't standalone functions because often you need to query strips
relative to each strip in collection.
Use SEQ_collection_expand() to query strips relative to each strip
in collection. These will be merged to original collection.
Use SEQ_collection_merge() to merge 2 collections
To iterate collection elements use macro SEQ_ITERATOR_FOREACH()
This API is quite specific, but I think it is best suited for tasks
that are usualy solved in sequencer codebase.
Old sequencer iterator has been completely removed.
SEQ_ALL_BEGIN and SEQ_ALL_END macros re-use new iterator design.
As initial use for this iterator select_grouped_effect_link()
function has been rewritten. It was not only broken, but also it used
DNA fields to aid iterating strips.

This is fixed by not doing interpolation with pixels outside of source

Such fix doesn't cover cropped images which are currently cropped by

GOP size and quality are adjusted for h264 codec.
These new values are based on result of benchmark on 9 random files:
https://docs.google.com/spreadsheets/d/1nOyUGjoVWUyhQ2y2lAd8VtFfyaY1wQNGj1krCCNbk7Y/edit?usp=sharing
Reducing quality to 50 reduces proxy filesize by about 2x on average
and has no significant impact on decoding performance.
Increasing GOP size from 2 to 10 also reduces proxy filesize 2x-3x
while scrubbing is only about 8% slower. It is still around 100FPS
with 1920x1080 media.
This is unfortunately about 50% slower than MJPEG, but this can be
improved with `fastdecode` tune applied to libx264 encoder
Quite surprisingly h264 codec presets had little influence on proxy
building performance as well as proxy filesize. So far it looks that
FFmpeg does initialize encoder in different way then Blender.
This applies mot only for presets but for tune and profile libx264
setting.
Once this issue is resolved, performance of proxies may be optimized
further.
