Need help to get timeline TC of certain effects

[RitaLee79]

Hi, im trying to extract certain data from exported aaf. I need to know the timecode of certain effects, for example, stabilizations, motion fxs and fluid morphs. I already can discover the effects with this code, but i need help on how to get the timecode in timeline:

`
with aaf2.open(aaf_file, 'r') as f:

for mob in f.content.compositionmobs():
    if mob.usage and 'TopLevel' in mob.usage:
        timeline = mob
        for slot in timeline.slots:
            if slot.media_kind == 'Picture':
                for comp in slot.segment.property_entries.values():
                    if 'Components' in comp.name:
                        for item in comp.value:
                            if item.name == 'OperationGroup':
                                print(item.operation.name)
                            elif item.name == 'Transition':
                                for prop in item.property_entries.values():
                                    if prop.name == 'OperationGroup':
                                        print(prop.value.operation.name)

`

Thank you very much for your awesome work !!

I think I have resolved my problem, tomorrow I'll check and fix with a real aaf but for now I wrote this:

`

import aaf2
from collections import defaultdict
from pprint import pprint

aaf_file = 'test.aaf'

effect_report = defaultdict(list)
frame_rate = None
start_frame = None
frame_counter = 0

with aaf2.open(aaf_file, 'r') as f:

    for mob in f.content.compositionmobs():
        if mob.usage and 'TopLevel' in mob.usage:
            timeline = mob
            for prop in timeline.property_entries.values():
                if prop.name == 'MobAttributeList':
                    for val in prop:
                        if val.name == 'SEQUERNCE_FORMAT_STRING':
                            frame_rate = int(val.value.rsplit('/', 1)[1])
                            break
                    else:
                        continue
                    break

            for slot in timeline.slots:
                if not start_frame and slot.segment.name == 'Timecode'\
                        and slot.segment.fps == frame_rate:
                    start_frame = slot.segment.start
                if slot.media_kind == 'Picture':
                    for comp in slot.segment.components.value:
                        if comp.name == 'OperationGroup':
                            effect_report[comp.operation.name].append(frame_counter + start_frame)
                            frame_counter += comp.length
                        elif comp.name == 'Transition':
                            trans_name = comp.property_entries[6145].value.operation.name
                            center_frame = comp.length // 2
                            effect_report[trans_name].append(frame_counter + start_frame - center_frame)
                            frame_counter -= comp.length
                        else:
                            frame_counter += comp.length

pprint(effect_report)
print(frame_counter, frame_rate, start_frame)
